The SGEO stationary satellite propulsion system uses electric power to expel the Xenon at a very high velocity in order to generate thrust. Earlier versions of the system used pyro technique valves which were fired before the satellite was launched. OHB Sweden decided to upgrade to HAM-LET’s UCV diaphragm valve due to its extremely clean operation and high reliability.

High-pressure high-flow models from HAM-LET’s Ultra-Clean Valve Series are made to UHP (Ultra High Purity) specifications. These models come with end connections in two alternative sizes, 1/4” and 1/2” as standard. With their compact design, these valves can comfortably perform in high-pressure, high-flow applications including their use as shut-off valves at pressures up to 21 MPa (3,060 psi). They are supplied with a large choice of fluid-specific seat materials to meet all needs.
